Re: [Scilab-users] How to produce a filled staircase plot
Under Scilab-5.5.2 xfpoly rescale the graph automatically as plot does
A little more simple (efficient?) code:
t = [ 0 2 5 10 12 17 20 30 35 45 60]'*0.1;
N = [20 18 15 14 12 9 6 4 3 2 1]';
t2=matrix([t' t($); t' t($)],-1,1);
N2=matrix([0 N'; N' 0],-1,1)
clf;
xfpoly(t2,N2);
h = gce();
h.line_mode = "off";
h.background = color('gray');
plot(t2(2:$-1),N2(2:$-1),'black', t2(2:$-1),21*exp(-t2(2:$-1)/2),'red');

Hello Raphael,
Nice plot, but sadly it doesn't rescale.
Do you have an idea how to make it fit the axes, to rescale automatically?
You can calculate your data_bounds and set them after plotting.
Alernatively, use my method that does not rely on xfpoly, but on plot
that rescales automatically:
//I want to staircase plot N(Decay_times)
N=[N2,N2-cumsum(ones(Decay_times))+1];
Np1=[N2-cumsum(ones(Decay_times))+1,0];
Ns=matrix([N;Np1],2*prod(size(N)));
Decay_times=[0,Decay_times];
D_t=matrix([Decay_times;Decay_times],2*prod(size(Decay_times)));
//in the end, I plot Ns(D_t)
Ns=[0;Ns];
D_t=[0;D_t];
//plot it
plot(D_t,Ns, 'k-');
//fill the bacground
e=gce();
e.children.polyline_style=1;
e.children.closed='off';
e.children.background=color('gray');

Thank you Serge for this solution, but it does not work for me: the "bars" in my case are not regular.
I am simulating an exponential random decay: starting from a number N0, my
population decreases by jumps of N0->N0-1 that occur at random times, following
an exponential law (see the attached plot).
For the moment, I just build my polygon by hand, but it adds quite a lot of
"noise" on top of the code that I intent to show to my students.
I was hoping for a cleaner solution.
Thanks anyway,
